Remove App Passwords

If you lose a device or stop using an app that was authorized with an App Password, we recommend revoking its App Password so that no one can access your Google Account from that device.

App passwords allow apps or devices that don’t support 2-Step Verification codes to access your Google Account. If you use 2-Step Verification and accessed your Google Account from an app or device like Gmail on your iPhone or iPad, you probably used an App Password.

Note: If you have the latest operating system on your iPhone, iPad, or Mac, you will no longer have to use App passwords to use 2-Step Verification.
